2 "So You Think You Can Dance" contestants rushed to hospital!

People:
Two dancers in the Top 4 of Fox’s So You Think You Can Dance collapsed at rehearsals Saturday and had to be rushed by ambulance to nearby Cedars Sinai Hospital–just days before the reality series season finale.
“Two went in [Saturday] and so there was no more rehearsals, and today [Sunday] all the rehearsals were called off,” ballroom expert and SYTYCD judge Mary Murphy confirmed to PEOPLE at Fox’s 2008 Teen Choice Awards in L.A. on Sunday. “The kids are completely dehydrated – two of them. I’m sure they’re doing a lot of blood work to see if there’s anything else.”
A source close to the show said that the two dancers are out of the hospital, doing better and will return to rehearsals Monday. Reps for Fox had no comment and did not release the identities of the two dancers.
